This deletes a big ol' chunk of code related to letters. It's not everything—there are still a few things that might be tied to sms/email—but it's the the heart of letters function. SMS and email function should be untouched by this.
Areas affected:
- Things obviously about letters
- PDF tasks, used for precompiling letters
- Virus scanning, used for those PDFs
- FTP, used to send letters to the printer
- Postage stuff
https://marshmallow.readthedocs.io/en/stable/upgrading.html#schemas-are-always-strict
`.load` doesn't return a `(data, errors)` tuple any more - only data is
returned. A `ValidationError` is raised if validation fails. The code
now relies on the `marshmallow_validation_error` error handler to handle
errors instead of having to raise an `InvalidRequest`. This has no
effect on the response that is returned (a test has been modified to
check).
Also added a new `password` field to the `UserSchema` so that we don't
have to specially check for password errors in the `.create_user` endpoint
- we can let marshmallow handle them.
We were using the Draft4Validator in one place, so this updates it to
the Draft7Validator instead.
The schemas were mostly using draft 4 of the JSON schema, though there
were a couple of schemas that were already of version 7. This updates
them all to version 7, which is the latest version fully supported by
the jsonschema Python package. There are some breaking changes in the
newer version of the schema, but I could not see anywhere would these
affect us. Some of these schemas were not valid in version 4, but are
now valid in version 7 because `"required": []` was not valid in earlier
versions.
This is enough to update a notification in DB:
1. First create a notification in the UI and sent it.
2. Then reset its attributes to pretend it's for Reach.
update notifications set
sent_at = null,
sent_by = null,
notification_status='sending'
where id='some-uuid';
3. Change "notification_id" to "<some-uuid>" in the code.
4. Call the boilerplate endpoint for Reach callbacks.
curl -X POST localhost:6011/notifications/sms/reach
Interestingly there's no foreign key constraint on "sent_by" in the
DB, so this just works: the notification is updated.
Last year we had an issue with the daily limit cache and the query that was populating it. As a result we have not been checking the daily limit properly. This PR should correct all that.
The daily limit cache is not being incremented in app.notifications.process_notifications.persist_notification, this method is and should always be the only method used to create a notification.
We increment the daily limit cache is redis is enabled (and it is always enabled for production) and the key type for the notification is team or normal.
We check if the daily limit is exceed in many places:
- app.celery.tasks.process_job
- app.v2.notifications.post_notifications.post_notification
- app.v2.notifications.post_notifications.post_precompiled_letter_notification
- app.service.send_notification.send_one_off_notification
- app.service.send_notification.send_pdf_letter_notification
If the daily limits cache is not found, set the cache to 0 with an expiry of 24 hours. The daily limit cache key is service_id-yyy-mm-dd-count, so each day a new cache is created.
The best thing about this PR is that the app.service_dao.fetch_todays_total_message_count query has been removed. This query was not performant and had been wrong for ages.
This is mostly useful for letters.
For templated letters sent via interface, whether one-offs
or CSV uploads, we do not give our users a way to set client reference.
Still, they often have a placeholder with reference that we could use
to set client_reference field.
Why is this helpful?
When letter is returned, or when we experience some printing issues,
often it is difficult to identify letters after the retention period.
This change will make it easier for some users to identify letters.
It will have more impact if we inform our users of this in template
editing guidance.
